Wavelength to Color: lColor, learn more about your light

Shows what color light will appear based on its wavelength in nm (nanometers) or its frequency, or energy in Hertz, Joules, eV or its wavenumber. Also provides quick unit conversion to all these different units. For any wavelength of light, it will also tell you, roughly, what part of spectrum it is in: UV, IR, Visible, x-ray, gamma-ray, radio etc.

Great for High School, AP, College or University Chemistry, Physics or Biology. Spectroscopist's best mobile tool for laser or incoherent spectroscopy!
